Too long : The details of your history aren't noted. More likely than not, at 26 years of age far better options are available for treatment of your pinched nerve/radiculopathy/disc herniation. Long term hydrocodone will cause physical dependance & neurophysiological changel in just about anyone. See a pain management / spine surgeon team who can help you get off the meds & to work out a better plan of care.
